  • Patent number: 8603095
    Abstract: Systems for use in total knee arthroplasty include a cutting guide having only a single slot. The single slot is configured to be positioned adjacent an anterior side of the medial compartment of the knee joint with no portion positioned adjacent an anterior side of the lateral compartment of the knee joint. The single slot is adapted to guide an oscillating saw blade across the knee bone from the medial compartment to resect at least a portion of the lateral compartment. The system also includes a total knee arthroplasty implant adapted to be implanted on the resected surface.

  • Patent number: 8430932
    Abstract: A system for use in a total knee arthroplasty procedure can include a first cutting guide, an alignment guide and a femoral prosthetic implant. The first cutting guide can include at least one planar guide surface adapted to guide a cutting tool to cut femur. The alignment guide can contact the femur and provide for markings to be made in the femur that dictate a location and orientation of the first cutting guide. The implant is adapted to be implanted on the resected femur. The implant can have an inwardly protruding structure to provide medial-lateral fixation stability, and can have an anterior fixation path that diverges proximally away from a long axis of the femur and a posterior fixation path that converges proximally towards the long axis such that the posterior fixation path and anterior fixation path converge toward one another proximally of a distal contact surface.
